when setting up your own bitcoin lightning node / channels, can someone explain the different ways you could lose some / all of your bitcoin that you lock up in channels?

- forced closures (i’ve heard are particularly bad during high fee environments)
- not backing up channel state and node on the other side of the channel uses previous state of channel (i think watchtowers are meant to prevent this)

anything else? and how do you best prevent / protect against these risks?
